The omentum was so much wasted, that nothing but its blood-vessels could

be perceived.

The stomach was inflamed, both on its outside and inside. It contained a

quantity of bile of the same consistence, but of a blacker colour than

that which was found in the gall bladder. Its villous coat, like that of

the duodenum, was covered with fuzzy and slimy matter. It moreover

appeared to be distended or swelled. This peculiarity in the inner coat

of the stomach was universal in all the bodies that were opened, of

persons who died of this disease.

The lungs, instead of being collapsed, were inflated as in inspiration.

They were all over full of black or livid spots. On these spots were to

be seen small vesicles or blisters, like those of an erysipelas or

gangrene, containing a yellow humour.

The blood-vessels in general seemed empty of blood, even the vena cava

and its branches; but the vena portarum was full and distended as usual.

The blood seemed _collected_ in the _viscera_; for upon cutting the lungs

or sound liver or spleen, they bled freely.

The brain was not opened in this body, but it was not affected in three

others whose brains were examined.

Dr. Mackittrick, in his inaugural dissertation, published at Edinburgh in

the year 1766, "De Febre Indiæ Occidentalis, Maligna Flava," or upon the

yellow fever of the West-Indies, says, that in some of the patients who

died of it, he found the liver sphacelated, the gall bladder full of

black bile, and the veins turgid with black fluid blood. In others he

found the liver no ways enlarged, and its "texture only vitiated." The

stomach, the duodenum, and ilium, were remarkably inflamed in all cases.

The pericardium contained a viscid yellow serum, and in a larger quantity

than common. The urinary bladder was a little inflamed. The lungs were

sound.

Dr. Hume, in describing the yellow fever of Jamaica, informs us, that in

several dead bodies which he opened, he found the liver enlarged and

turgid with bile, and of a pale yellow colour. In some he found the

stomach and duodenum inflamed. In one case he discovered black spots in

the stomach, of the size of a crown piece. To this account he adds, "that

he had seen some subjects opened, on whose stomachs _no marks of

inflammation_ could be discovered; and yet these had excessive vomiting."

Dr. Lind has furnished us with an account of the state of the body after

death, in his short history of the yellow fever, which prevailed at

Cadiz, in the year 1764. "The stomach (he says), mesentery, and

intestines, were covered with gangrenous spots; there were ulcers on the

orifice of the stomach, and the liver and lungs were of a putrid colour

and texture[54]."

[54] Diseases of Warm Climates, p. 125.

To these accounts of the morbid appearances of the body after death from

the yellow fever I shall only add the account of several dissections,

which was given to the public in Mr. Brown's Gazette, during the

prevalence of this epidemic, by Dr. Physick and Dr. Cathrall.

"Being well assured of the great importance of dissections of morbid

bodies in the investigation of the nature of diseases, we have thought it

of consequence that some of those dead of the present prevailing

malignant fever should be examined; and, without enlarging on our

observations, it appears at present sufficient to state the following

facts.

"1st. That the brain in all its parts has been found in a natural

condition.

"2d. That the viscera of the thorax are perfectly sound. The blood,

however, in the heart and veins is fluid, similar, in its consistence, to

the blood of persons who have been hanged, or destroyed by electricity.

"3d. That the stomach, and beginning of the duodenum, are the parts that

appear most diseased. In two persons who died of the disease on the 5th

day, the villous membrane of the stomach, especially about its smaller

end, was found highly inflamed; and this inflammation extended through

the pylorus into the duodenum, some way. The inflammation here was

exactly similar to that induced in the stomach by acrid poisons, as by

arsenic, which we have once had an opportunity of seeing in a person

destroyed by it.

"The bile in the gall-bladder was quite of its natural colour, though

very viscid.

"In another person, who died on the 8th day of the disease, several spots

of extravasation were discovered between the membranes, particularly

about the smaller end of the stomach, the inflammation of which had

considerably abated. Pus was seen in the beginning of the duodenum, and

the villous membrane at this part was thickened.

"In two other persons, who died at a more advanced period of the disease,

the stomach appeared spotted in many places with extravasations, and the

inflammation disappeared. It contained, as did also the intestines, a

black liquor, which had been vomited and purged before death. This black

liquor appears clearly to be an altered secretion from the liver; for a

fluid in all respects of the same qualities was found in the gall

bladder. This liquor was so acrid, that it induced considerable

inflammation and swelling on the operator's hands, which remained some

days. The villous membrane of the intestines, in these last two bodies,

was found inflamed in several places.

"The liver was of its natural appearance, excepting in one of the last

persons, on the surface of which a very few distended veins were seen:

all the other abdominal viscera were of a healthy appearance.

"The external surface of the stomach, as well as of the intestines, was

quite free from inflammation; the veins being distended with blood, which

appeared through the transparent peritonium, gave them a dark colour.

"The stomach of those who died early in the disease was always

contracted; but in those who died at a more advanced period of it, where

extravasations appeared, it was distended with air.

"P. S. PHYSICK,

"J. CATHRALL."

I have before remarked, that these dissections were made early in the

disease, and that Dr. Annan attended a dissection of a body at

Bush-hill, some time afterwards, in which an unusual turgescence appeared

in the vessels of the brain.

Thus far have I delivered the history of the yellow fever, as it affected

the human body with sickness and death. I shall now mention a few of

those circumstances of public and private distress which attended it. I

have before remarked, that the first reports of the existence of this

fever were treated with neglect or contempt. A strange apathy pervaded

all classes of people. While I bore my share of reproach for "terrifying

our citizens with imaginary danger," I answered it by lamenting "that

they were not terrified enough." The publication from the college of

physicians soon dissipated this indifference and incredulity. Fear or

terror now sat upon every countenance. The disease appeared in many parts

of the town, remote from the spot where it originated; although, for a

while, in every instance, it was easily traced to it. This set the city

in motion. The streets and roads leading from the city were crowded with

families flying in every direction for safety to the country. Business

began to languish. Water-street, between Market and Race-streets, became

a desert. The poor were the first victims of the fever. From the sudden

interruption of business they suffered for a while from poverty as well

as from disease. A large and airy house at Bush-hill, about a mile from

the city, was opened for their reception. This house, after it became the

charge of a committee appointed by the citizens on the 14th of September,

was regulated and governed with the order and cleanliness of an old and

established hospital. An American and French physician had the exclusive

medical care of it after the 22d of September.

The disease, after the second week in September, spared no rank of

citizens. Whole families were confined by it. There was a deficiency of

nurses for the sick, and many of those who were employed were unqualified

for their business. There was likewise a great deficiency of physicians,

from the desertion of some, and the sickness and death of others. At one

time there were but three physicians who were able to do business out of

their houses, and at this time there were probably not less than 6000

persons ill with the fever.

During the first three or four weeks of the prevalence of the disease I

seldom went into a house the first time, without meeting the parents or

children of the sick in tears. Many wept aloud in my entry, or parlour,

who came to ask for advice for their relations. Grief after a while

descended below weeping, and I was much struck in observing that many

persons submitted to the loss of relations and friends without shedding a

tear, or manifesting any other of the common signs of grief.

A cheerful countenance was scarcely to be seen in the city for six weeks.

I recollect once, in entering the house of a poor man, to have met a

child of two years old that smiled in my face. I was strangely affected

with this sight (so discordant to my feelings and the state of the city)

before I recollected the age and ignorance of the child. I was confined

the next day by an attack of the fever, and was sorry to hear, upon my

recovery, that the father and mother of this little creature died a few

days after my last visit to them.

The streets every where discovered marks of the distress that pervaded

the city. More than one half the houses were shut up, although not more

than one third of the inhabitants had fled into the country. In walking

for many hundred yards, few persons were met, except such as were in

quest of a physician, a nurse, a bleeder, or the men who buried the dead.

The hearse alone kept up the remembrance of the noise of carriages or

carts in the streets. Funeral processions were laid aside. A black man,

leading or driving a horse, with a corpse on a pair of chair wheels, with

now and then half a dozen relations or friends following at a distance

from it, met the eye in most of the streets of the city, at every hour of

the day, while the noise of the same wheels passing slowly over the

pavements, kept alive anguish and fear in the sick and well, every hour

of the night[55].

[55] In the Life of Thomas Story, a celebrated preacher among the

friends, there is an account of the distress of the city, in its

infant state, from the prevalence of the yellow fever, in the

autumn of 1699, nearly like that which has been described. I shall

insert the account in his own words. "Great was the fear that fell

on all flesh. I saw no lofty or airy countenance, nor heard any

vain jesting to move men to laughter. Every face gathered

paleness, and many hearts were humbled, and countenances fallen

and sunk, as such that waited every moment to be summoned to the

bar, and numbered to the grave." The same author adds, that six,

seven, and sometimes eight, died of this fever in a day, for

several weeks. His fellow-traveller, and companion in the

ministry, Roger Gill, discovered upon this occasion an

extraordinary degree of christian philanthropy. He publicly

offered himself, in one of the meetings of the society, as a

sacrifice for the people, and prayed that "God would please to

accept of his life for them, that a stop might be put to the

contagion." He died of the fever a few days afterwards.

But a more serious source of the distress of the city arose from the

dissentions of the physicians, about the nature and treatment of the

fever. It was considered by some as a modification of the influenza, and

by others as the jail fever. Its various grades and symptoms were

considered as so many different diseases, all originating from different

causes. There was the same contrariety in the practice of the physicians

that there was in their principles. The newspapers conveyed accounts of

both to the public, every day. The minds of the citizens were distracted

by them, and hundreds suffered and died from the delays which were

produced by an erroneous opinion of a plurality of diseases in the city,

or by indecision in the choice, or a want of confidence in the remedies

of their physician.

The science of medicine is related to every thing, and the philosopher as

well as the christian will be gratified by knowing the effects of a great

and mortal epidemic upon the morals of a people. It was some alleviation

of the distress produced by it, to observe its influence upon the

obligations of morality and religion. It was remarked during this time,

by many people, that the name of the Supreme Being was seldom profaned,

either in the streets, or in the intercourse of the citizens with each

other. But two robberies, and those of a trifling nature, occurred in

nearly two months, although many hundred houses were exposed to plunder,

every hour of the day and night. Many of the religious societies met two

or three times a week, and some of them every evening, to implore the

interposition of Heaven to save the city from desolation. Humanity and

charity kept pace with devotion. The public have already seen accounts of

their benevolent exercises in other publications. It was my lot to

witness the uncommon activity of those virtues upon a smaller scale. I

saw little to blame, but much to admire and praise in persons of

different professions, both sexes, and of all colours. It would be

foreign to the design of this work to draw from the obscurity which they

sought, the many acts of humanity and charity, of fortitude, patience,

and perseverance, which came under my notice. They will be made public

and applauded elsewhere.

But the virtues which were excited by our calamity were not confined to

the city of Philadelphia. The United States wept for the distresses of

their capital. In several of the states, and in many cities and villages,

days of humiliation and prayer were set apart to supplicate the Father of

Mercies in behalf of our afflicted city. Nor was this all. From nearly

every state in the union the most liberal contributions of money,

provisions, and fuel were poured in for the relief and support of such

as had been reduced to want by the suspension of business, as well as by

sickness and the death of friends.

The number of deaths between the 1st of August and the 9th of November

amounted to four thousand and forty-four. I shall here insert a register

of the number which occurred on each day, beginning on the 1st of August,

and ending on the 9th of November. By comparing it with the register of

the weather it will show the influence of the latter on the disease.

Several of the deaths in August were from other acute diseases, and a few

in the succeeding months were from such as were of a chronic nature.

[56] In the above accounts there is a deficiency of returns from

several grave-yards of 163.

From this table it appears that the principal mortality was in the second

week of October. A general expectation had obtained, that cold weather

was as fatal to this fever as heavy rains. The usual time for its arrival

had come, but the weather was still not only moderate, but warm. In this

awful situation, the stoutest hearts began to fail. Hope sickened, and

despair succeeded distress in almost every countenance. On the

_fifteenth_ of October, it pleased God to alter the state of the air.

The clouds at last dropped health in showers of rain, which continued

during the whole day, and which were succeeded for several nights

afterwards by cold and frost. The effects of this change in the weather

appeared first in the sudden diminution of the sick, for the deaths

continued for a week afterwards to be numerous, but they were of persons

who had been confined before, or on the day in which the change had taken

place in the weather.

The appearance of this rain was like a dove with an olive branch in its

mouth to the whole city. Public notice was given of its beneficial

effects, in a letter subscribed by the mayor of Philadelphia, who acted

as president of the committee, to the mayor of New-York. I shall insert

the whole of this letter. It contains, besides the above information, a

record of the liberality of that city to the distressed inhabitants of

Philadelphia.

"SIR,

"I am favoured with your letter of the 12th instant, which I have

communicated to the committee for the relief of the poor and afflicted of

this city.

"It is with peculiar satisfaction that I execute their request, by

making, in their name, on behalf of our suffering fellow-citizens, the

most grateful acknowledgements for the seasonable benevolence of the

common council of the city of New-York. Their sympathy is balm to our

wounds.

"We acknowledge the Divine interposition, whereby the hearts of so many

around us have been touched with our distress, and have united in our

relief.

"May the Almighty Disposer of all events be graciously pleased to protect

your citizens from the dreadful calamity with which we are now visited;

whilst we humbly kiss the rod, and improve by the dispensation.

"The part, sir, which you personally take in our afflictions, and which

you have so pathetically expressed in your letter, excites in the breasts

of the committee the warmest sensations of fraternal affection.

"The refreshing rain which fell the day before yesterday, though light,

and the cool weather which hath succeeded, appear to have given a check

to the prevalence of the disorder: of this we have satisfactory proofs,

as well in the decrease of the funerals, as in the applications for

removal to the hospital.

"I have, at your request, this day drawn upon you, at sight, in favour of

the president and directors of the Bank of North America, for the sum of

five thousand dollars, the benevolent donations of the common council of

the city of New-York.

"With sentiments of the greatest esteem and regard,

"I am, sir,

"Your most obedient humble servant,

"MATTH. CLARKSON.

_"Philadelphia, Oct. 17, 1793._

_"Richard Varick, mayor of the city of New-York."_

It is no new thing for bilious fevers, of every description, to be

checked or subdued by _wet_ and _cold_ weather.

The yellow fever which raged in Philadelphia in 1699, and which is taken

notice of by Thomas Story in his journal, ceased about the latter end of

October, or the beginning of November. Of this there are satisfactory

proofs, in the register of the interments in the friends' burying-ground,

and in a letter, dated November 9th, old style, 1699, from Isaac Norris

to one of his correspondents, which his grandson, Mr. Joseph P. Norris,

politely put into my hands, with several others, which mention the

disease, and all written in that memorable year in Philadelphia. The

letter says, "It has pleased God to put a stop to our sore visitation,

and town and country are now generally healthy." The same disease was

checked by wet and cold weather in the year 1741. Of this there is a

proof in a letter from Dr. Franklin to one of his brothers, who stopped

at Burlington, on his way from Boston to Philadelphia, on account of the

fever, until he was assured by the doctor, that a thunder gust, which had

cooled the air, had rendered it safe for him to come into the city[57].

Mr. Lynford Lardner, in a letter to one of his English friends, dated

September 24, 1747, old style, after mentioning the prevalence of the

fever in the city, says, "the weather is now much cooler, and those under

the disorder revive. The symptoms are less violent, and the fever

gradually abates."

[57] From a short note in the register of the interments in the

friends' burying-ground, it appears that the fever this year made

its first appearance in the month of June. The following is a copy

of that note: "12th of the 6th month (O. S.), 1741, a malignant

yellow fever now spreads much." Besides that note, there is the

following: "25th of the 7th month (O. S.), 1741, many who died of

the above distemper were persons lively, and strong, and in the

prime of their time."

I have in vain attempted to procure an account of the time of the

commencement of cold weather in the autumn of 1762. In the short history

of the fever of that year, which I have inserted from my note book, I

have said that it continued to prevail in the months of November and

December. The register of the interments in the friends' burying-ground

in those months confirms that account. They were nearly as numerous in

November and December as in September and October, viz. in September 22,

in October 27, in November 19, and in December 26.

The bilious remitting fever of 1780 yielded to cool weather, accompanied

by rain and an easterly wind[58].

[58] Vol. i.

Sir John Pringle will furnish ample satisfaction to such of my readers as

wish for more proofs of the efficacy of heavy rains, and cold weather, in

checking the progress and violence of autumnal remitting fevers[59].

[59] P. 5, 56, 180, and 323.

From the 15th of October the disease not only declined, but assumed more

obvious inflammatory symptoms. It was, as in the beginning, more

necessarily fatal where left to itself, but it yielded more certainly to

art than it did a few weeks before. The duration of it was now more

tedious than in the warmer weather.

There were a few cases of yellow fever in November and December, after

the citizens who had retired to the country returned to the city.

I heard of but three persons who returned to the city being infected with

the disease; so completely was its cause destroyed in the course of a few

weeks.

In consequence of a proclamation by the governor, and a recommendation by

the clergy of Philadelphia, the 12th of December was observed as a day

of thanksgiving throughout the state, for the extinction of the disease

in the city.

It was easy to distinguish, in walking the streets, the persons who had

returned from the country to the city, from those who had remained in it

during the prevalence of the fever. The former appeared ruddy and

healthy, while the latter appeared of a pale or sallow colour.

It afforded a subject of equal surprise and joy to behold the suddenness

with which the city recovered its former habits of business. In the

course of six weeks after the disease had ceased, nothing but fresh

graves, and the black dresses of many of the citizens, afforded a public

trace of the distress which had so lately prevailed in the city.
